A year ago today, Tesla’s big battery in South Australia began dispatching power to the state’s grid, one day ahead of schedule. By most accounts, the world’s largest lithium-ion battery has been a remarkable success. But there are some concerns that have so far escaped scrutiny.

But not every aspect of Tesla’s big battery earns a big tick. The battery’s own credentials aren’t particularly “green”, and by making people feel good about the energy they consume over summer, it arguably sustains an unhealthy appetite for energy consumption.

The problem of lithium-ion batteries

The Hornsdale Power Reserve is made up of hundreds of Tesla Powerpacks, each containing 16 “battery pods” similar to the ones in Tesla’s Model S vehicle. Each battery pod houses thousands of small lithium-ion cells – the same ones that you might find in a hand-held device like a torch.

It’s important that Tesla is held account to the above claim. A CSIRO report found that in 2016, only 2% of lithium-ion batteries were collected in Australia to be recycled offshore.

However, lithium-ion batteries aren’t the only option. Australia is leading the way in developing more sustainable alternative batteries. There are also other innovative ways to store energy, such as by harnessing the gravitational energy stored in giant hanging bricks.

Solving symptoms, not problems

Tesla’s big battery was introduced at a time when the energy debate was fixated on South Australia’s energy “crisis” and a need for “energy security”. After a succession of severe weather events and blackouts, the state’s renewable energy agenda was under fire and there was pressure on the government to take action.

On February 8, 2017, high temperatures contributed to high electricity demand and South Australia experienced yet another widespread blackout. But this time it was caused by the common practice of “load-shedding”, in which power is deliberately cut to sections of the grid to prevent it being overwhelmed.

Since the battery’s inception the theme of “summer” (a euphemism for high electricity demand) has followed its reports in media.

The combination of extreme heat and high demand is very challenging for an electricity distribution system. Big batteries can undoubtedly help smooth this peak demand. But that’s only solving a symptom of the deeper problem – namely, excessive electricity demand.

Time to talk about energy demand

These concerns are most likely not addressed in the national conversation because of the urgency to move away from fossil fuels and, as such, a desire to keep big batteries in a positive light.

But as we continue to adopt renewable energy technologies, we need to embrace a new relationship with energy. By avoiding these concerns we only prolong the very problems that have led us to a changed climate and arguably, make us ill-prepared for our renewable energy future.

The good news is that the big battery industry is just kicking off. That means now is the time to talk about what type of big batteries we want in the future, to review our expectations of energy supply, and to embrace more sustainable demand.

My latest holiday plan has gone flop – the back packing holiday is a no-goer. Reason? It would seem from all reports that the Tops to Myalls Heritage Trail has been abandoned, with parts of the route now so overgrown as to be unrecognizable. I have been told of walkers in recent times having to back track a fair distance when the way ahead was no longer able to be walked. So as disappointing as it is I have abandoned the trail myself and will now do something else.

With time running out for a settled option, I have decided to fall back on an earlier idea and that is to visit the Cathedral Rocks National Park and possibly do some further walks at the Dorrigo National Park. I have booked a vehicle (car rental) for the trip so things are fairly settled now as far as the destination is concerned. I am now going to put some meat on the bones of my idea and draw up an itinerary, Google Map, etc. So some real detail of what I plan to do will be coming over the next few weeks.

This isn’t going to be an expensive holiday or a long one, but is mean’t to be a simple time-out break and one that will allow me to plan some much bigger holidays for later in the year and into the coming year also.
